My query is a query with a bunch of nested Select statements.

When i run the query in PL/SQL developer it returns results fine. Direct copy / paste.

Try simplifying the SELECT statement to use fewer nested queries. I don't know for sure, but you might be limited to a single SELECT keyword when using a DataAdapter...? Anyone, feel free to correct me here!

Hello,
Can you paste the db query here. There might be something related to string manipulation in C# or .net related issue.

Cheers.

My registration page contains fields,register submit button and also a user control inside this page. i have username, password fields and Login submit button in this user control. in both user control and registration page i have used RequiredFieldValidator. so, when i try to login to my application by providing userid and password it is not entering into the application because it is validating registration page required fields and also if i fill all required fields in registration page and when i click on register submit button the records are not saving it is validating login screen required fields. how do i correct this problem? since i cannot validate fields in javascript because it is a multilingual application. pls. help me out.

Try implementing the validation controls in the user login control itself.

Try reading Inter-Process Communication in .NET Using Named Pipes, Part 2.

A.,

I don't think anyone on this board will give a shrink-wrapped solution to your problem. Interprocess communication can get messy depending on how you implement it. If you don't already understand what you're doing, then you need to get some education regarding the matter.

However, you have a lucky star over your head because I found two articles right here on CodeProject that you can read. You will then know for what you ask and two methods for doing it in the Win32 API.

You are looking for .NET Remoting[^] or Socket Programming[^].

You'd have to P/Invoke SendMessage[^] then.

.Net Remoting is the answer if both the applications are written in .Net(which i assume so).
Here is the link for a basic over view of .net remoting Click Here

I keep hearing people say to use Remoting to send data/messages between two processes/programs/whatever yet everything I've seen talks about running a routine in the server. Nobody talks about how to get the server to respond to a message.

In other words - you have an app that wants to send a message to another app saying 'There's new data available for you.' With remoting you can call a routine on the server but then how does the server know that there's been a change? It seems to me like the only thing you are doing is calling a remote routine but it doesn't provide communication with the host; the routine is segregated from the host.

Am I reading this wrong?

RichTextBox Fun?

The following code works just fine on my "test" form, but when i put the code in the REAL application i get a selection rectangle, rather than the nice text color change i get with this code:

richTextBox1.AppendText("This" + System.Environment.NewLine);
richTextBox1.AppendText("seems" + System.Environment.NewLine);
richTextBox1.AppendText("to" + System.Environment.NewLine);
richTextBox1.AppendText("work." + System.Environment.NewLine);

string mySearchLetters = textBox1.Text;
int index = richTextBox1.Find(mySearchLetters);
label1.Text = mySearchLetters + " was found in pos " + index.ToString();
if (index >= 0)
richTextBox1.SelectionColor = System.Drawing.Color.Orange;

I'm thinking that maybe there is a "property" set on the real application that prevents this code from working but i can not find it. i compare the control properties, line-for-line and they seem to be identical.

Any ideas?

I take it your trying to highlight the position and length of the string you typed in?

This code won't work because your not changing the .SelectStart and .SelectionLength properties to actually select the string you want to change with .SelectionColor.

richTextBox1.SelectionStart = pos;
richTextBox1.SelectionLength = mySearchLetters.Length;
richTextBox1.SelectionColor = Color.Orange;

It turns out the solution was even simpler .. there WAS a property that was messing things up. All i had to do was set HideSelection to true !!!

The pretty orange text was hidden under the selection rectangle ... go figure ... lol.

Thanks for responding, Dave.
